Career Reinvention After 50: From Software Engineer to AI

You are not starting over. You are translating decades of engineering experience into the work that is emerging now. Career Reinvention After 50 is a practical roadmap for experienced software engineers, architects, technical leads, testers, managers, and consultants who want to move into applied artificial intelligence without pretending their past no longer matters.Duane Cash combines production-software experience, AI engineering, invention, architecture, and a real midlife career transition to show how experienced technologists can build current capability and credible proof. You will learn how to choose an AI engineering lane, understand language models, retrieval-augmented generation, tools and agents, evaluation, guardrails, production architecture, and responsible deployment.The book also addresses the parts that technical tutorials ignore: age bias, confidence after a layoff, resume positioning, LinkedIn, interviews, compensation, consulting, portfolio strategy, and sustainable reinvention.Inside you will find 28 practical Reinvention Labs, a twelve-week learning plan, an AI engineer skills matrix, a flagship project specification, 50 interview questions, case studies, and a practical glossary. Your experience is not the obstacle. Untranslated experience is. This book helps you build the bridge.
